Trial summary

The main purpose of the study is to better understand how specific proteins/markers in blood, urine, synovial fluid (a lubricating fluid secreted by the membrane lining the joints), and joint tissue are involved in osteoarthritis of the knee. Read more about this study

About this study

Official title: Investigation of Biomarkers in an Exploratory Study in Patients With Osteoarthritis of the Knee Undergoing Total Knee Replacement Surgery

The main purpose of the study is to better understand how specific proteins/markers in blood, urine, synovial fluid (a lubricating fluid secreted by the membrane lining the joints), and joint tissue are involved in osteoarthritis of the knee. The aim is to investigate if there is a correlation between x-ray results, specific proteins/markers and different types of pain in patients with osteoarthritis of the knee. The study consists of 3 visits over 3-20 days and the last visit will be the day of surgery.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of patients with upregulation of IL-6 or the IL-6 signalling pathway in the knee.

    Measured: 3-20 days prior to day 1 (surgery) and day 1 (surgery) .

Secondary outcomes (5)
  1. Biomarkers in synovial fluid, synovial membrane, and cartilage.

    Measured: Day 1 (surgery).

  2. Biomarkers in blood and urine.

    Measured: 3-20 days prior to day 1 (surgery) and day 1 (surgery).

  3. Biomarkers by Magnetic Resonance Imaging (MRI).

    Measured: 1-5 days prior to day 1 (surgery).

  4. Polymorphisms in 10 specific genes.

    Measured: 3-20 days prior to day 1 (surgery) or at any time in the study.

  5. WOMAC (Western Ontario and McMaster Osteoarthritis Index) variables and NPQ (Neuropathic Pain Questionnaire) variables.

    WOMAC consists of 3 subscales with a total of 24 questions regarding pain, stiffness and difficulty in performing daily activities. A VAS (Visual Analogue Scale) will be used for the patient to report the severity of the symptoms on the target knee. Endpoints are marked "No pain" (0 mm) and " Extreme pain" (100 mm) on a paper PRO (Patient Reported Outcome) questionnaire. The less pain scored the better outcome.

    NPQ accesses 12 different pain intensities. 0 represents no intensity and 100 represents worst intensity imaginable. The less intensity the better outcome.

    Measured: 3-20 days prior to day 1 (surgery) and 1-5 days prior to day 1 (surgery).

Questions about this trial

What is this clinical trial studying?

An observational study of Osteoarthritis of the Knee, run by AstraZeneca at 6 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Jun 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in Canada, Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of patients with upregulation of IL-6 or the IL-6 signalling pathway in the knee. (time frame: 3-20 days prior to day 1 (surgery) and day 1 (surgery) .). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01611441, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jun 2012.
